Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical non-invasive detection device. Background Art

[0002] When a patient suffers from hemorrhagic shock, a hemodynamic detection device is usually used. Using sensors and ultrasound probes, the patient's electrocardiogram (ECG), non-invasive blood pressure, pulse oxygen saturation, and echocardiography are monitored to achieve early identification of hemorrhagic shock, disease monitoring, and efficacy evaluation. In the process of using an ultrasound probe to perform echocardiographic monitoring of the patient, in order to reduce the frictional resistance between the probe and the skin and ensure the stability of the transmitted sound waves, medical staff are usually required to apply coupling agent to the patient's skin or the outside of the probe before performing echocardiographic monitoring on the patient.

[0003] For example, the existing application number CN202010503320.4 belongs to the field of information monitoring technology, and discloses a non-invasive blood flow-based elderly heart failure monitoring and evaluation control system and method. The data acquisition module is used to use the BioZ non-invasive hemodynamic monitor to collect pleural fluid level TFC, stroke volume variability SVV and other hemodynamic parameters; the data calculation module is used to calculate the TFC / SVV value based on the detected relevant hemodynamic parameters; the monitoring and evaluation module is used to perform status assessment based on the detected pleural fluid level TFC, stroke volume variability SVV and other hemodynamic parameters and the calculated TFC / SVV value, and take different monitoring measures based on the corresponding evaluation results; the invention provides, for example, a non-invasive hemodynamic monitoring method, which is simple to operate and does not require special training for the tester; it has high repeatability and is highly consistent with the relevant parameters of the bedside hemodynamic monitoring system.

[0004] However, during the echocardiographic monitoring process, medical staff are required to repeatedly dip and apply the coupling agent, which is not only time-consuming and labor-intensive and affects the detection efficiency, but also easily causes the risk of cross-infection due to contamination of the coupling agent bottle. At the same time, it is also very easy for air to be drawn in and form bubbles when manually applying the coupling agent. The bubbles will produce a strong reflective interface, resulting in snowflake-like noise or irregular echo artifacts, affecting the image quality and the use effect and work efficiency of the detection device, causing interference in the judgment of the patient's condition. Summary of the Invention

[0005] In view of this, the present invention provides a medical non-invasive detection device, which ensures the uniformity of the coupling agent when applying, simplifies the operating steps of medical staff when testing patients, not only improves the detection efficiency, but also greatly avoids the risk of cross infection caused by contamination of the coupling agent bottle, greatly avoids the phenomenon of frequent wiping and re-application due to a large number of coupling agent bubbles, and interference with the judgment of the patient's condition due to poor image quality, shortens the detection time, and avoids the risk of contact dermatitis caused by repeated application of coupling agent, and interference with the judgment of the patient's condition due to poor image quality, not only shortens the detection time, but also avoids the risk of contact dermatitis caused by repeated application of coupling agent, further improving the use effect and work efficiency of the detection device.
